i post this question before some days but still no replay. yesterday i found solution. here is solution. for this we need to create one controller so once user click on apply credit button then we need to update quote.

code :

$balanceModel = Mage::getModel('enterprise_customerbalance/balance')
            ->setCustomerId($sessionCustomer->getCustomer()->getId())
            ->setWebsiteId(Mage::app()->getWebsite()->getId())
            ->loadByCustomer()->getAmount();
         if($balanceModel > 0):
            $cart = Mage::getModel('checkout/cart')->getQuote();
            $cart->setuse_customer_balance("1");
            $cart->save();
         endif;

that's it done.

Thanks
